FRUIT-JAR WRENCH.

Specification of Letters Patent.

Patented Nov. 29, 1910.

Application filed .Tune 22, 1910. Serial No. 568,303.

To all whom it may concern:

Be it known that we, LonY J. GnArFoR'r and PETER L. HOFFMAN, citizens of the United States, residing at New Carlisle, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Fruit-J ar Wrenches, of which the following is a specification.

This invention relates to jar wrenches for removing the screw caps from jars, and the principal object of the same is to provide a wrench of the type specified with novel cap clamping means adjustable with relation to the cap, thereby adapting the wrench for usein connection with jars of different sizes.

In carrying out the objects of the invention generally stated above it will be understood, of course, that the essential features thereof are necessarily susceptible of changes in details and structural arrangements, one preferred and practical embodiment of which is shown in the accompanying drawings, wherein Figure l is a top plan view of the improved jar wrench. Fig. 2 is a view in side elevation thereof.

Referrino` to said accompanying drawings by numeratls, it will be seen that the improved wrench comprises a body in the form of a, main clamping plate l, the outer edge of which is provided witha pendent gripping ange 2 that is curved on an arc of a circle and adapted to engage one portion of the periphery of a jar cap. Said plate l has the elongated handles 3 and l pivotally connected thereto, each handle having a depending auxiliary clamp 5 pivotally connected thereto. Said clamps are preferably formed of a fiat body plate, the rear edge of which is provided with a pendent gripping flange 6 that is curved on an arc of a circle. The clamps 5 are smaller than the plate l, and engage the jar cap at points opposite said plate, as indicated by dotted lines in the accompanying drawings.

In use, the handles are spread apart, and the plate l placed over the cap, as indicated in the drawings, and the handles brought together, which forces the clamps 5 into binding` engagement with the cap, so that by r0- tating the wrench, the cap can readily be removed from a jar, or placed in position thereon.

Clamps 5 being loosely pivoted to the handles, it will be readily seen that they automatically adjust themselves to the cap.

It will also be seen, that the method employed for connecting the clamps to the handles facilitates the use of the wrench on caps of various sizes.

What we claim as our invention is A jar wrench comprising a main clamping plate provided with a depending flange,

handles pivoted to said plate, and depending auxiliary clamping members pivoted to said handles and each provided with a depending flange.

In testimony whereof we afiix our signa tures in presence of two witnesses LORY J. GRAFFORT. PETER L. HCEFMAN. Witnesses:
